description:
A JSON parsing and generation library optimized for ease of use
and high performance.
.
Parsing performance with GHC 6.12.3 on a late 2010 MacBook Pro
(2.66GHz Core i7), for mostly-English tweets from Twitter's JSON
search API:
.
* English, 854 bytes: 29029 msg\/sec (23.6 MB/sec)
.
* English, 6.4 KB: 6407 msg\/sec (40.3 MB/sec)
.
* English, 31.2 KB: 1265 msg\/sec (38.8 MB/sec)
.
* English, 61.5 KB: 585 msg\/sec (35.2 MB/sec)
.
Handling heavily-escaped text is a little more work. Here is
parsing performance with Japanese tweets, where much of the text
is entirely Unicode-escaped:
.
* Japanese, 14.6 KB: 2227 msg\/sec (31.9 MB/sec)
.
* Japanese, 44.1 KB: 671 msg\/sec (29.6 MB/sec)
.
Encoding performance on the same machine and data:
.
* English, 854 bytes: 43439 msg\/sec (35.4 MB/sec)
.
* English, 6.4 KB: 7127 msg\/sec (44.8 MB/sec)
.
* Engish, 61.5 KB: 765 msg\/sec (46.0 MB/sec)
.
* Japanese, 14.6 KB: 4727 msg\/sec (67.5 MB/sec)
.
* Japanese, 44.1 KB: 1505 msg\/sec (64.8 MB/sec)
.
With GHC 7.0.2, the story is mixed: parsing is 20-40% slower than
GHC 6.12.3, while encoding performance ranges from about the same
to twice as fast (on numeric data).

(A note on naming: in Greek mythology, Aeson was the father of Jason.)
